Abstract
An air conditioning system for conditioning air in a plurality of enclosed areas in a building. Conditioned air at a relatively cold temperature level is supplied to a terminal for discharge into an area. The quantity of relatively cold temperature air discharged into the area is regulated in accordance with the temperature level therein. A control signal is generated, the magnitude thereof being indicative of the quantity of conditioned air discharged into the area. The magnitude of the control signal is monitored. Warm air supply means is activated when the magnitude of the control signal indicates that the quantity of the relatively cold temperature air being discharged into the area has decreased below a predetermined level.
Claims2
A method of operating an air conditioning system for conditioning air in a plurality of enclosed areas in a building comprising the steps of:
- delivering a stream of air conditioned to a relatively constant cold temperature level to a terminal provided in each of the areas;
- regulating the quantity of relatively cold conditioned air discharged into the area in accordance with the temperature level therein;
- generating a control signal, the magnitude thereof varying in accordance with the quantity of constant temperature conditioned air supplied to the area;
- monitoring the magnitude of the control signal;
- and
- activating a warm air supply terminal when the magnitude of the control signal indicates that the quantity of constant temperature relatively cold air discharged into the area has decreased below a predetermined level.
